public AbstractReferenceElementType()

Method Details

convertValue

public Reference convertValue(Object value)
                       throws BadItemTypeException

Description copied from class: AbstractElementType

Try to convert the given value, that is not of the managed type

Overrides:

convertValue in class AbstractElementType<Reference>

Parameters:

value - the value to convert

Returns:

the converted value or null if it's not possible.

Throws:

BadItemTypeException - if the given value is not compatible with the current type

toString

public String toString(Reference value)

Description copied from interface: ElementType

Cast a typed value to a String

Specified by:

toString in interface ElementType<Reference>

Overrides:

toString in class AbstractElementType<Reference>

Parameters:

value - the value to cast

Returns:

the String representation of the value

fromJSONForClient

public Object fromJSONForClient(Object json,
 DataContext context)

Description copied from interface: ElementType

Convert the given client side JSON object to the types value

Parameters:

json - the JSON object to convert

context - the context of the data to retrieve

Returns:

the typed value corresponding to the JSON object

_singleValueToJSON

protected Object _singleValueToJSON(Reference value,
 DataContext context)

Description copied from class: AbstractElementType

Convert the single value into a JSON object

Overrides:

_singleValueToJSON in class AbstractElementType<Reference>

Parameters:

value - the value to convert

context - The context of the data to convert

Returns:

The value as JSON

_singleValueFromXML

protected Reference _singleValueFromXML(Element element,
 Optional<Object> additionalData)

Description copied from class: AbstractElementType

Retrieves a single typed value from the given DOM node

Overrides:

_singleValueFromXML in class AbstractElementType<Reference>

Parameters:

element - the DOM element containing the single value

additionalData - additional data needed to get the typed value

Returns:

the value

_singleValueToSAX

protected void _singleValueToSAX(ContentHandler contentHandler,
 String tagName,
 Reference value,
 Optional<ViewItem> viewItem,
 DataContext context,
 AttributesImpl attributes)
                          throws SAXException

Description copied from class: AbstractElementType

Generates SAX events for the given single value

Overrides:

_singleValueToSAX in class AbstractElementType<Reference>

Parameters:

contentHandler - the ContentHandler that will receive the SAX events

tagName - the tag name of the SAX event to generate.

value - the single value to SAX

viewItem - The optional view item corresponding item that is currently saxed. This view item gives context for the SAX event that will be generated here.

context - The context of the data to SAX

attributes - the attributes for the SAX event to generate

Throws:

SAXException - if an error occurs during the SAX events generation

_compareMultipleValues

protected Stream<Triple<DataChangeType,DataChangeTypeDetail,String>> _compareMultipleValues(Reference[] value1,
 Reference[] value2)

Description copied from class: AbstractElementType

Compares the given multiple values and retrieves the changes as a stream of Triples. The Triples contains:

• the general type of the change (added, modified or removed) as a DataChangeType,
• some details about this change if possible (after or before for a date, more or less for a number, ...) as a DataChangeTypeDetail
• The data concerned by this change if not the element itself (or an empty String)

Overrides:

_compareMultipleValues in class AbstractElementType<Reference>

Parameters:

value1 - the 1st multiple value

value2 - the 2nd multiple value

Returns:

the changes between the two given multiple values as a stream of Triple. Retrieves an empty stream if there is no change

_compareSingleValues

protected Stream<Triple<DataChangeType,DataChangeTypeDetail,String>> _compareSingleValues(Reference value1,
 Reference value2)

Description copied from class: AbstractElementType

Compares the given single values and retrieves the changes as a stream of Triples. The Triple contains:

• the general type of the change (added, modified or removed) as a DataChangeType,
• some details about this change if possible (after or before for a date, more or less for a number, ...) as a DataChangeTypeDetail
• The data concerned by this change if not the element itself (or an empty String)

Overrides:

_compareSingleValues in class AbstractElementType<Reference>

Parameters:

value1 - the 1st single value

value2 - the 2nd single value

Returns:

the changes between the two given single values as a stream of Triple. Retrieves an empty stream if there is no change

isSimple

public boolean isSimple()

Description copied from interface: ElementType

Determines if this type is simple or not. A simple element type is a type of elements that can be edited in a grid

Returns:

true if the type is simple, false otherwise

Description copied from class: AbstractElementType

Determine if the JSON format has to be used in edition mode for this element type

Overrides:

_useJSONForEdition in class AbstractElementType<Reference>

Returns:

true if the JSON format has to be used, false otherwise
